1/N expansion technique and the Non-SU(3) intrinsic states of the sdg interacting boson model
Description
By utilizing the 1/N expansion technique, the SU(3)-symmetry breaking caused by boson energies is discussed for the sdg Interacting Boson Model, and the analytical expressions of the intrinsic states are given under the approximation in the order of 1/N. It is also shown that the many body theories for a interacting boson system, such as Hartree-Bose method, Tamm-Dancoff approximation and Cranked Hartree approximation, are all special cases of the 1/N expansion technique
